JONESBORO, Ga. -- A woman who is a social worker with DFCS bonded out of jail Sunday after being arrested a day earlier.

Jonesboro Police suspect Ericka Thompson was driving under the influence of cocaine and marijuana.

At the time, police say, she was transporting an adult with mental disabilities to an area group home.

The incident happened at around 4 p.m. during a routine traffic stop. The officer who pulled over Thompson said his automated license reader showed her tag as expired. He reported smelling a strong odor of marijuana. A subsequent search uncovered a bag of marijuana along with cocaine and oxycontin.

Thompson was not acting in an official capacity as an employee of [DFCS]... It is Department policy to maintain a drug-free workplace, in accordance with the Federal Drug-free Workplace Act and the Georgia Drug-free Public Work Force Act. As it would any employee accused of illegal activity, the Department will review the accusations against Ms. Thompson and determine the appropriate response once it has had an opportunity to fully understand the facts.

Chief Allen also complained that when his department tried to reach DFCS for help dealing with Thompson's passenger, who was stranded after he arrest, no one ever called him back.

"That's the protocol. We call DFCS, but I couldn't get the Clayton County office or anyone from the state to call us back," said Allen.

Police finally found a manager at the group home to respond.

11Alive News asked Fielding about the slow response complaint.

"Representatives from the Department have been in contact with local police to address any concerns they may have and ensure there are no gaps in communication," said Fielding.
